Quick answer: Ground support installation stacks LED cabinets from the floor using a base frame, truss towers or support bars, instead of hanging them. It is used when the venue cannot carry rigging loads. Stability depends on a level base, rear bracing, ballast and — outdoors — wind straps rated for local conditions.
Ground support LED systems are commonly used in:
- ngoài trời buổi hòa nhạc
- các sự kiện thể thao
- các giai đoạn tạm thời
- public festivals
- outdoor ceremonies
Compared with hanging systems, ground support structures usually prioritize:
- large screen scale
- khả năng chống gió
- tính ổn định về mặt kết cấu
Why Outdoor Wind Load Is So Important
Large outdoor LED walls face continuous environmental pressure from:
- gió
- rung động
- weather changes
- sự di chuyển của khán giả
Poor structural design may create serious safety risks.
This is why professional ground support systems require:
- structural calculation
- reinforced support systems
- proper ballast
- stable base construction
Why Large Screens Require More Structural Reinforcement
As screen size increases, structural pressure grows dramatically.
This becomes especially critical for:
- liên hoan ngoài trời
- các sự kiện tại sân vận động
- music concerts
- government celebrations
Large LED walls often require:
- steel reinforcement
- multi-point support
- wind resistance analysis
Ground Support Setup Steps
- Level the base plates or ground frame on firm, flat ground.
- Erect rear truss towers or support bars to the required height.
- Stack cabinets from the bottom row upward, locking each connection.
- Add rear braces and ballast according to screen height and wind exposure.
- Outdoors, use wind straps and plan to power down and lower the screen in strong wind.
- Check verticality and flatness before connecting power and signal.
DDW Engineer Notes: Ground support LED screen installation
In outdoor stage projects, wind resistance is often more important than screen resolution.
Many structural risks appear not during normal weather, but during sudden environmental changes.
Ground support engineering should always prioritize safety before visual scale.
FAQ
When should I choose ground support instead of hanging?
Choose ground support when the venue roof or truss cannot carry the LED screen weight, or for outdoor stages without rigging points.
How high can a ground-stacked LED screen be?
Many ground support systems reach about 5–8 m, depending on bracing, ballast and wind load. Taller screens usually need a truss structure.
Is ground support safe outdoors?
Yes, when properly braced, ballasted and wind-strapped. Always follow the wind limits and lower or secure the screen in strong wind.
